Background & Aim: Lemon verbena (Lippia citriodora H.B.K.) is a richly scented herb and has a long history as a sacred and medicinal plant. Select an appropriate medium in tissue culture is a necessity for success Experimental: To evaluate the effect of 10 medium of previous researches for Lippia micropropagation (1- MS medium supplemented with BAP (3 mgL-1) + IBA ...

sugar type and growth regulators are essential fundamental components of tissue culture media. in this study, different concentrations of some carbohydrate and growth regulators during anther culture and producing somatic embryo of datura stramonium l. was investigated in ms medium. the ms medium supplemented with 0.5 mgl-1 kinetin and 2 mgl-1 2,4-d, and also the medium supplemented with 0.25 m...

Article Type: Full Length Research Article The aim of this investigation was to confirm a trickling filter filled with gravel as an alternative biological process over conventional high cost treatment process with regard to nutrient reduction from brewery wastewater. Steady state evaluation of the trickling filter aerobic and anaerobic biofilm system for nutrient removal was made. The results o...

To better understand the metabolism of sulfur-containing amino acids, which likely plays a key role in a variety of cell functions, in Entamoeba histolytica, we searched the genome data base for genes encoding putative orthologs of enzymes known to be involved in the metabolism. The search revealed that E. histolytica possesses only incomplete cysteine-methionine conversion pathways in both dir...

A rabbit model was used to compare the effect on the blood-brain barrier of the intracarotid injection of two new contrast media: iohexol, a nonionic monomer, and iodixanol, a nonionic dimer. It was hypothesized that the low osmolality of iodixanol (272 mOsm/kg at 300 mgl/ml) would cause less disruption of the blood-brain barrier than the relatively higher osmolality of iohexol (690 mOsm/kg at ...

In the present study, an efficient protocol has been developed for callus induction and production of RA in callus culture of Satureja khuzistanica for the first time. In vitro callus induction was achieved from young shoot tip explants cultured on MS and B5 media supplemented with different concentrations of IBA (0.1, 1.0, 2.0 and 5.0 mgl-1) solely or in combination with cytokinins BAP and KIN...

A variety of lipid radicals are formed under oxidative stress development. The further oxidation of these radicals leads to formation of numerous aldehydes. They can form postsynthetic modifications in proteins and nucleic acids that disrupt their functions. In the present study aldehydes role in the formation of oxidative stress parameters in rat thymocytes was investigated. Two models were us...

Since 2001 a superconducting cyclotron for proton therapy has been designed in collaboration with the National Superconducting Cyclotron Laboratory (NSCL) at ACCEL Instruments GmbH [1]. The design is based on a NSCL proposal originating from 1993 [2]. In the recent years two cyclotrons of this type were built, tested as far as magnetic and cryogenic properties are concerned and installed at the...

in this study, rainbow trout (oncorhynchus mykiss) eggs were treated with effective doses of  daenensis thyme, thymus daenensis (20, 10 and 5 mgl-1) and mentha, mentha longifolia (10, 5 and 2.5 mgl-1), during incubation period (20 days) until hatching for 30 minutes per every other day as constant flow bath treatment method. the mortality level in normal control (without any treatment) was sign...
